Protocol numbers and sockopt options

Protocol numbers are based on both RFC 1700 p.7 and the Internet Assigned Numbers Authority (IANA) http://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml

Those are to be used with the added sockopt options. The various options have been
tested with wireshark.
